A molecular bond results from an electron being transferred from one
atom to another. Which type of bond holds these atoms together?
a) electroneutral
b) ionic
c) covalent
d) hydrogen - Correct Answer - ionic
After a rainy day, a leaf has small droplets of water on its surface. Which
property of water is this an example of?
a) cohesion
b) density
c) good solvent
d) temperature stability - Correct Answer - cohesion
A plastic water bottle is filled with water and placed in the freezer. The
next day the frozen water has expanded, causing the plastic bottle to
rupture. Which characteristic of water is this an example of?
a) cohesion
,2|Page
b) density
c) good solvent
d) temperature stability - Correct Answer - density
The initial biochemical transformation of glucose during cellular
respiration occurs within the cytoplasm of the cell. Glucose is
transformed into glucose-6-phosphate as ATP is converted into ADP and
a free phosphate group.
What is happening to energy in this initial step of glycolysis?
a) Energy is being created in the form of glucose-6-phosphate.
b) Energy is being destroyed as ATP is converted to ADP.
c) Energy is being transformed from chemical potential energy to kinetic
energy.
d) Energy is being released from ATP to power the conversion of
glucose. - Correct Answer - Energy is being released from ATP to power
the conversion of glucose.
In the human body, muscle fibers metabolize sugars to produce energy.
Fast-twitch muscle fibers, like those used during short-term, vigorous
exercise, carry out an anaerobic process that produces less energy per
sugar molecule processed. Which metabolic process do fast-twitch
muscle fibers carry out?
a) fermentation
b) respiration
c) photosynthesis
,3|Page
d) oxidation - Correct Answer - fermentation
Some cells need to maintain a set concentration of Na + and K + ions.
These cells are able to do this with the help of the Na/K pump, which
transports these ions from areas of low concentration to areas of high
concentration (against their concentration gradient). Na + is pumped out,
and K + is pumped in. Which type of membrane transport is involved in
this action?
a) diffusion
b) endocytosis
c) passive transport
d) active transport - Correct Answer - active transport
Chromosomes are structures that contain hereditary material that will be
passed from one generation to the next. According to this information,
which organic molecule must be present in chromosomes?
a) glucose
b) RNA
c) DNA
d) lipid - Correct Answer – DNA
A cell has divided its chromosomes into two new nuclei. The
cytoskeleton of the cell is currently pinching the cell in the middle to
form two new cells. In which stage of the cell cycle is this cell?
, 4|Page
a) G1
b) synthesis
c) G2
d) cytokinesis - Correct Answer - cytokinesis
Sister chromatids are being separated and moving towards opposite
poles of the cell. Which stage of mitosis is this?
a) Telophase
b) Anaphase
c) Prophase
d) Metaphase - Correct Answer - Anaphase
A cell undergoing meiosis is currently dividing. The two new daughter
cells will be haploid, but the DNA they contain is still replicated. The
homologous chromosomes have separated and are ready to start the
second division, but they have not yet begun the second round of
division. Which stage of the cell cycle is this cell in?
a) Metaphase I
b) Telophase I
c) Metaphase II
d) Telophase II - Correct Answer - Telophase I
Homologous pairs of chromosomes have separated into two cells. Sister
chromatids in each cell have not yet lined up in the middle of the cell.
